The 2026 AI Data Landscape: Proxies Are Now AI Infrastructure

The web scraping market hit an estimated $1.17 billion in 2026, according to Mordor Intelligence. That figure is not driven by traditional price monitoring or lead generation alone. The bulk of new demand comes from AI teams building RAG systems, fine-tuning LLMs on fresh domain data, and deploying autonomous agents that browse the web on behalf of users.

The numbers behind this shift are hard to ignore. Akamai reported that AI bot traffic surged over 300% across its network in 2025. Adobe measured a 4,700% year-over-year increase in generative AI traffic by mid-2025. The AI agents market is projected to reach $48.3 billion by 2030 at a 43.3% CAGR. Scrapingdog estimates that nearly half of all internet traffic will be bots by the end of 2026.

Meanwhile, the 2026 State of Web Scraping report from Apify found that 65.8% of web scraping professionals increased their proxy usage year-over-year, and 58.3% reported higher proxy spending. This is not a cost problem. It is a signal that proxy quality directly determines data pipeline reliability. For AI workloads, a blocked request is not just a failed scrape. It is a gap in your model's knowledge.

RAG Pipelines Need Fresh Web Data

Retrieval-Augmented Generation has become the standard architecture for grounding LLM outputs in real-world facts. Instead of retraining a model every time information changes, a RAG pipeline retrieves relevant documents from an external knowledge base at query time and injects them into the prompt. The result is more accurate, up-to-date responses without the cost of full fine-tuning.

The bottleneck is the retrieval layer. RAG systems need continuous web ingestion to keep their vector stores current. A pricing page that changed two hours ago, a regulatory filing published this morning, a competitor's new product listing: if your scraper cannot access these sources reliably, your RAG system serves stale answers. As Forage AI notes, for RAG-based systems, stale data actively degrades output quality.

This is where proxy infrastructure becomes part of the AI stack. A RAG pipeline running bulk ingestion jobs against dozens of domains needs intelligent IP rotation to avoid rate limits and blocks. Mobile proxies routed through real carrier networks produce traffic patterns that are nearly indistinguishable from organic user behavior, which means higher success rates per request and fewer gaps in your knowledge base.

Agentic AI and Web Browsing: Why Agents Need Carrier-Grade IPs

Agentic AI represents a fundamental shift from static scraping to dynamic web interaction. Tools like Google's Chrome auto browse (powered by Gemini), OpenAI's Atlas browser, and open-source frameworks like Browser Use and Crawl4AI allow AI agents to navigate websites autonomously: clicking links, filling forms, scrolling through results, and synthesizing information across multiple pages in a single session.

This is structurally different from traditional scraping. A conventional scraper sends stateless HTTP requests. An AI agent maintains a multi-step browsing session that can span minutes and dozens of page loads, all under a single identity. If that identity gets flagged mid-session, the entire task fails, and the agent must restart from scratch.

Datacenter IPs are a poor fit for this pattern. Anti-bot systems in 2026 use behavioral fingerprinting, TLS analysis, and IP reputation scoring. Datacenter addresses carry inherently lower trust scores. In real-world testing, datacenter IPs show ban rates around 27%, compared to roughly 4% for mobile carrier IPs and 6% for residential IPs. For agentic workflows where session continuity matters, that difference is not marginal. It is the difference between a pipeline that works and one that fails unpredictably.

5G mobile proxies solve this by routing agent traffic through physical SIM cards on real carrier networks. The IP addresses carry the same trust scores as any mobile user browsing from their phone. Combined with sticky sessions that hold an IP for the duration of a multi-step task, this gives AI agents the identity stability they need to complete complex workflows without interruption.

Architecture: Segmented Proxy Routing for AI Data Pipelines

Not every request in an AI pipeline needs the same level of proxy quality. A well-designed system segments traffic by target sensitivity and routes each segment through the appropriate proxy tier. This keeps costs down while maintaining high success rates where they matter most.

Here is a practical routing architecture for AI data pipelines:

The principle is straightforward: route your hardest targets through your highest-trust IPs, and send bulk refresh jobs through lower-cost infrastructure. This mirrors how enterprise data teams structure their proxy stacks for production workloads. With Illusory, you can implement this segmentation on a single platform by assigning different proxy endpoints to different pipeline stages.

Session Control and IP Rotation for Multi-Step Agent Tasks

AI agents that browse the web need session management that matches their task structure. A research agent collecting data across five pages of search results needs a consistent IP for the entire workflow. A RAG crawler indexing hundreds of product pages needs rapid rotation to distribute requests and avoid rate limits.

Sticky Sessions for Agentic Workflows

Use sticky sessions when your agent maintains state across multiple page loads. This is critical for tasks that involve login flows, paginated results, or multi-step form submissions. Illusory supports sticky sessions up to 30 minutes on dedicated 5G connections, long enough for most agentic browsing tasks. You control session duration at the connection level, so each agent task can define its own session window.

Rotating IPs for Bulk Ingestion

For high-volume RAG ingestion, rotate IPs on every request. This distributes your footprint across the carrier's IP pool and prevents any single address from accumulating enough requests to trigger rate limits. The key is pairing rotation speed with request pacing. Sending 1,000 requests per second through rotating IPs still looks like a bot if every request hits the same domain. Spread requests across domains and add randomized delays between 1-3 seconds for best results.

For a deeper breakdown of rotation strategies, see our guide on IP rotation practices for AI agents.

Training Data Quality: How Dedicated Mobile IPs Reduce Noise

Data quality is the silent killer of AI pipelines. AI-powered scrapers can achieve accuracy rates up to 99.5% and extraction speeds 30-40% faster than traditional methods. But that accuracy assumes the scraper can actually reach the target page and receive its real content. When requests get blocked, redirected to CAPTCHAs, or served degraded responses, the downstream data quality drops.

Shared proxy pools amplify this problem. When your IP addresses are used simultaneously by dozens of other customers, some running aggressive or low-quality scraping jobs, the reputation of those IPs degrades. You end up with higher block rates, more CAPTCHAs, and more noise in your training data.

Dedicated mobile infrastructure eliminates this variable. With Illusory, each customer gets access to bare-metal 5G hardware with real SIM cards, not shared pools. Your IP reputation is yours alone. This means consistent success rates, clean page responses, and data that does not need extra filtering before it enters your embedding pipeline or fine-tuning dataset.

Cost Optimization: Mobile vs. Residential Proxies in AI Workloads

Mobile proxies cost more per gigabyte than residential alternatives. In 2026, mobile proxy pricing ranges from approximately $3.90 to $9.00 per GB depending on provider and volume, while residential proxies range from $1.50 to $4.00 per GB. The question is not which is cheaper. It is which delivers lower cost per successful request for your specific workload.

The cost calculation shifts when you factor in retries, CAPTCHA solving fees, and data cleaning overhead. A mobile proxy that costs $6/GB but completes 96% of requests on the first attempt is often cheaper per clean data point than a residential proxy at $2/GB that fails 15% of the time against protected targets. Run the math on your specific targets before defaulting to the cheapest per-GB option.

Getting Started: Connecting Illusory to AI Scraping Frameworks

Illusory's 5G mobile proxies work with any HTTP/HTTPS-compatible client. Here is how to connect to the most popular AI scraping and RAG frameworks in 2026.

Crawl4AI (RAG Pipelines)

Crawl4AI is the top open-source crawler for LLM-ready data, producing clean Markdown output that feeds directly into vector databases like Pinecone, Weaviate, or Chroma. To route Crawl4AI through Illusory, pass your proxy credentials in the crawler configuration:

proxy="http://username:[email protected]:port"

Set this in the BrowserConfig when initializing AsyncWebCrawler. Crawl4AI handles headless browser rendering, JavaScript execution, and content extraction. Illusory handles the IP layer, ensuring each request arrives from a real 5G carrier address.

LangChain and LlamaIndex

Both frameworks support custom document loaders that accept proxy configuration. For LangChain, configure the proxy in your web scraping loader's request parameters:

proxies={"https": "http://username:[email protected]:port"}

This applies to WebBaseLoader, AsyncHtmlLoader, and custom loaders built on requests or aiohttp. For LlamaIndex, set the proxy in your data connector's HTTP client configuration. Both frameworks then handle chunking, embedding, and vector storage downstream.

Scrapy and Playwright

For teams running custom scraping infrastructure, configure Illusory as a standard HTTP proxy. In Scrapy, set HTTP_PROXY and HTTPS_PROXY in your project settings or use a custom downloader middleware that rotates between Illusory endpoints. In Playwright, pass the proxy object when launching the browser:

proxy={"server": "http://proxy.illusory.io:port", "username": "user", "password": "pass"}

Playwright is especially relevant for agentic workflows where the AI controls a headless browser. Combined with Illusory's sticky sessions, this setup gives your agent a stable 5G identity for the entire browsing session.

FAQ

Do I need mobile proxies for every part of my AI data pipeline?

No. Use mobile proxies for high-value targets with strong anti-bot protections and for agentic browsing sessions that require session continuity. Route bulk ingestion of unprotected content through residential or datacenter proxies to manage costs. The segmented routing architecture described above gives you the best balance of reliability and efficiency.

How do 5G mobile proxies differ from residential proxies for AI scraping?

Mobile proxies route traffic through real SIM cards on carrier networks (T-Mobile, AT&T, Verizon), producing IP addresses with the highest trust scores. Residential proxies use IP addresses assigned to home ISP connections, often sourced through peer-to-peer networks. Mobile IPs have lower block rates (~4% vs ~6%) and better session stability, but cost more per GB. For a detailed comparison, see our AI web scraping with mobile proxies guide.

Can I use Illusory proxies with OpenAI's browsing tools or ChatGPT plugins?

Illusory works with any tool that supports HTTP/HTTPS proxy configuration. If you are building agents using the OpenAI Assistants API with web browsing capabilities, or using frameworks like Browser Use that control a headless browser, you can route that browser traffic through Illusory. Direct integration with ChatGPT's built-in browsing is not supported, as that runs on OpenAI's own infrastructure.

What session duration should I use for AI agent tasks?

It depends on the task. Short research queries (single page fetch) need no session persistence. Multi-step agent workflows that span 5-20 page loads should use sticky sessions of 10-30 minutes. For long-running monitoring agents, rotate IPs periodically (every 15-30 minutes) to balance trust score maintenance with detection avoidance.

How much bandwidth does a typical RAG ingestion pipeline consume?

A RAG pipeline crawling 10,000 pages per day, with an average page size of 500KB after rendering, consumes roughly 5GB of bandwidth daily. At Illusory's mobile proxy rates, that is a predictable cost you can model against the value of keeping your LLM's knowledge base current. High-volume pipelines indexing 100,000+ pages will benefit from the tiered routing approach to optimize spend across proxy types.
